Born to a working-class wool weaver in the port city of Genoa, Italy, Cristoforo Colombo apprenticed as a sailor and went to sea as early as age ten. A self-taught and curious man, Colombo lived by his wits and rose in the heady world of 15th-century sea traders, until he hit upon an ingenious idea: He would outflank the Mohammedan Turks and reach the East Indies by sailing west across the Ocean Sea. After weathering nearly a decade of rejection and failure, in 1492 Colombo won the support of the Spanish Crown and set off on an uncertain journey that inadvertently opened a New World, laying the foundation for that most glittering daughter of the Western heritage: America.
